A buckle 104 adapted to the ratchet teeth 103 is provided in the channel. The buckle 104 is connected to the lock head 101 through an elastic connecting piece 105.

[0017] The temperature sensor 2 is located on the lock head 101; the cable 10 temperature detection device includes two cable ties 1 arranged in sequence along the axial direction perpendicular to the belt body 102. The lock heads 101 of the two cable ties 1 are connected by a connecting plate 3, and the temperature sensor 2 is located on the connecting plate 3; a power supply device 4, a communication device 5, and an alarm device 6 are provided on the connecting plate 3. The power supply device 4 is respectively connected to the temperature sensor 2, the communication device 5, and the alarm device 6. The power supply device 4 is used to supply power to the temperature sensor 2, the communication device 5, and the alarm device 6; the temperature sensor 2 is respectively connected to the communication device 5 and the alarm device 6. The temperature sensor 2 is used to monitor the temperature of the cable 10. The communication device 5 is used to remotely contact the staff. The alarm device 6 uses an indicator light, which is used for the staff to quickly identify the position of the alarm detection device among many cables 10; the channel extends along the axial direction of the belt body 102; the elastic connecting piece 105 extends along the axial direction of the belt body 102, and both ends of the elastic connecting piece 105 are fixedly connected to the buckle 104 and the lock head 101 respectively; the teeth 103 on both sides along the axial direction of the belt body 102 can be arranged oppositely and inclined along the axial direction of the belt body 102.

[0018] The cable tie 1 is wound around the cable 10, and the end of the belt body 102 away from the lock head 101 passes through the channel on the lock head 101. The teeth 103 pass through the buckle 104 in sequence. The elastic connecting piece 105 drives the buckle 104 to reciprocate between the depressions and protrusions of the teeth 103 until the cable tie 1 is fastened to the cable 10. The elastic connecting piece 105 drives the buckle 104 to return to its original position and lock the teeth 103. The cable tie 1 successfully fastens the temperature sensor 2 to the cable 10; moving the buckle 104, the elastic connecting piece 105 bends, the buckle 104 moves away from the teeth 103, and the end of the belt body 102 close to the lock head 101 pulls the belt body 102 out of the channel, the cable tie 1 is separated from the cable 10, and the temperature sensor 2 is separated from the cable 10.

[0019] As Figure 1 shown, a card slot communicating with the channel is opened on the lock head 101. The buckle 104 is slidably arranged in the card slot, and a wrench 106 is fixedly arranged on the side of the buckle 104 away from the channel; the one-way inclined teeth 103 prevent the cable tie 1 from loosening under the action of the thermal expansion and contraction of the cable 10. The wrench 106 is convenient for driving the buckle 104 away from the teeth 103, so as to facilitate the tightening and loosening of the cable tie 1; the elastic connecting piece 105 is located in the card slot; the side of the teeth 103 close to the lock head 101 can be a vertical surface perpendicular to the axial direction of the belt body 102, and the side of the teeth 103 away from the lock head 101 can be an inclined surface inclined along the axial direction of the belt body 102, so as to prevent the cable tie 1 from sliding in the channel when the cable 10 expands thermally, resulting in the cable tie 1 being unable to be fastened to the cable.

[0020] Pull the wrench 106. The wrench 106 drives the buckle 104 away from the ratchet teeth 103 through the elastic connecting piece 105, and the end of the self-carrying body 102 close to the lock head 101 pulls the belt body 102 until the belt body 102 is completely pulled out from the channel. The cable tie 1 is detached from the cable 10, and the temperature sensor 2 is detached from the cable 10. Then release the wrench 106.

[0022] The cable tie 1 is fastened on the cable 10, and the elastic pieces 7 are closely attached to the surface of the cable 10; when the cable tie 1 is detached from the cable 10, the elastic pieces 7 return to their original positions under the elastic action; when the cable 10 heats up and expands, the surface of the cable 10 exerts extrusion on the cable tie 1 and the elastic pieces 7, and the elastic pieces 7 contract under the pressure and approach the cable tie 1 to ensure that the cable tie 1 is always fastened on the cable 10; when the cable 10 cools and contracts, the elastic pieces 7 move towards the cable 10 under the elastic action and are closely attached to the surface of the cable 10 to ensure that the cable tie 1 is always fastened on the cable 10.

[0023] As Figure 1 、 Figure 2 and Figure 3 shown, a sliding groove is formed on the lock head 101, and a guide rod 8 is slidably arranged in the sliding groove. One end of the guide rod 8 facing the bundling part 107 passes through the return spring 9 and is fixedly connected to the temperature sensor 2; the axial direction of the sliding groove is perpendicular to the axis of the channel.

[0024] The cable tie 1 is fastened on the cable 10, and the cable 10 extrudes the temperature sensor 2. The guide rod 8 moves along the sliding groove towards the end away from the bundling part 107, and the return spring 9 contracts. The temperature sensor 2 is closely attached to the surface of the cable 10; when the cable tie 1 is detached from the cable 10, the return spring 9 expands and drives the guide rod 8 and the temperature sensor 2 to move along the sliding groove towards the bundling part 107 until the temperature sensor 2 returns to its original position; when the cable 10 heats up and expands, the surface of the cable 10 exerts extrusion on the temperature sensor 2, and the guide rod 8 moves along the sliding groove towards the end away from the bundling part 107, and the return spring 9 contracts. The temperature sensor 2 is always closely attached to the surface of the cable 10; when the cable 10 cools and contracts, the return spring 9 expands and drives the guide rod 8 and the temperature sensor 2 to move along the sliding groove towards the bundling part 107, and the temperature sensor 2 is always closely attached to the surface of the cable 10.

[0025] During the actual production process, the cable tie 1 is wound around the cable 10, and the end of the tape body 102 away from the lock head 101 passes through the channel on the lock head 101. The locking teeth 103 pass through the buckle 104 in sequence, and the elastic connecting piece 105 drives the buckle 104 to reciprocate between the depressions and protrusions of the locking teeth 103 until the cable tie 1 is fastened on the cable 10. The elastic connecting piece 105 drives the buckle 104 to return to its original position and lock the locking teeth 103, and the cable tie 1 successfully fastens the temperature sensor 2 on the cable 10; the elastic piece 7 is closely attached to the surface of the cable 10, and the cable 10 presses the temperature sensor 2.
